I've been playing with arithmetic (I'm one of the unwashed hordes
writing books).
The JDK Change Notes say "the meaning of floating point % got clarified."
To what?
The alpha spec says that a % b on floats is equivalent to:
a - ((int)(a / b) * b)
However, that's not what a % b is currently behaving like, and I'm getting
really bizarre results. 12.5 % 7.5, for example, is now -1.5. Huh?
What's the new formula for floating-point modulus?
